Well, our current thinking is to stay away from the ++ and --
operators in RPG IV to avoid problems with side effects.

But, we have no problems with the idea of +=, -=, /=, etc.
A+=1 really isn't much more difficult for programmers to code
than A++, and avoids the temptation of coding A++ deep within
an expression.

Hmmm.  But would we want to allow EVAL A,B,C += 1  ?!?
